Late Reconstruction of Patellar Ligament Ruptures Using Ilizarov External Fixation

Chronic patellar ligament ruptures, on which failed reconstruction attempts have been made, cause structural changes in the quadriceps mechanisms with marked fixed proximal migration of the patella. Before reconstruction, the position of the patella must be normalized. When using Ilizarov principles and an Ilizarov external fixator to treat these ruptures, full weightbearing and range of motion can be maintained throughout the pre- and postreconstruction period. This previously unreported technique has been used in 2 patients with chronic patellar ligament ruptures in whom reconstruction attempts had failed. Successful results obtained with this procedure warrant its consideration for this rare but disabling problem.

Femoral derotation for increased hip anteversion. A new surgical technique with a modified Ilizarov frame

We describe a technique of femoral derotation osteotomy performed according to the Ilizarov principles of percutaneous corticotomy and fixation with a frame. We performed 24 femoral osteotomies in 16 patients, four with cerebral palsy and 12 with idiopathic femoral anteversion. All had rapid union and there were few complications. The advantages of the method include early ambulation, good control of rotation and axial alignment, and minimal scarring.

Distraction of the frontal bone outside the cranial plane: a rabbit model.

Distraction of the frontal bone outside the cranial plane using the Ilizarov principle was performed in 17 22-week-old New Zealand white rabbits. Five rabbits had frontal bone osteotomy only and were in the control group; 5 rabbits were placed in the sham control group and had frontal bone osteotomy plus application of a customized headgear appliance; and 7 rabbits were placed in the experimental group, which underwent frontal bone osteotomy application of the headgear and distraction. The frontal bone was elevated 1 mm every other day for a period of 8 weeks, and the animals were then killed. Cephalometry was performed both preoperatively and at the end of the 8-week period. Histological examination of the skulls was also performed. The experimental group showed a significantly elevated frontal bone compared to the sham control group (p < 0.05). Callous bone filled the distracted segment, which united the frontal bone with the cranial plane. Therefore, frontal bone advancement by distraction osteogenesis is possible using this rabbit model.
